Do these allow us to stick advertisement?
I have come some near Hoan Kiem Lake, but they did not accept us to stick any where.

you just feel free to ask them to do that. I have been to all of these places and i saw a lot of advertisements there. By the way a friend of mine from America is coming to Vietnam at the end of this month. She wants to become an English teacher here. Could you help???

We are happy to invite her to work with us. Does she have Education Degree? or any Certificate related to teaching?
